Natural Product‐Derived Vesicles in Nanotherapeutics

Journal of Extracellular Vesicles, Volume 15, Issue 9, September 2026.
Natural product‐derived vesicles (NPVs) are an emerging nature‐based nanotherapeutic that can deliver bioactive metabolites into the target site and induce beneficial mechanisms. A practical, chronological bench‐to‐bedside approach throughout the entire NPV development process is expected to resolve challenges encountered in NPV studies.
